Pathogenic Huntingtin Repeat Expansions in Patients with Frontotemporal Dementia and Amyotrophic Lateral Sclerosis.
We examined the role of repeat expansions in the pathogenesis of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) by analyzing whole-genome sequence data from 2,442 FTD/ALS patients, 2,599 Lewy body dementia (LBD) patients, and 3,158 neurologically healthy subjects. Pathogenic expansions (range, 40-64 CAG repeats) in the huntingtin (HTT) gene were found in three (0.12%) patients diagnosed with pure FTD/ALS syndromes but were not present in the LBD or healthy cohorts. We replicated our findings in an independent collection of 3,674 FTD/ALS patients. Postmortem evaluations of two patients revealed the classical TDP-43 pathology of FTD/ALS, as well as huntingtin-positive, ubiquitin-positive aggregates in the frontal cortex. The neostriatal atrophy that pathologically defines Huntington's disease was absent in both cases. Our findings reveal an etiological relationship between HTT repeat expansions and FTD/ALS syndromes and indicate that genetic screening of FTD/ALS patients for HTT repeat expansions should be considered
Perceived corruption and individuals’ life satisfaction: The mediating role of Institutional Trust Marco
Corruption degrades the quality of institutions, increases economic inequality and limits growth. Recent studies indicate that corruption is also associated with lower satisfaction with life. This research examines a potential explanation for this association and investigates the role of institutional trust in mediating the linkage between perceived corruption and satisfaction with life. Specifically, in two studies, we tested the novel hypothesises that perceived corruption affects life satisfaction indirectly by undermining individuals’ confidence in institutions. Study 1 (N = 251) involved an opportunity sample from the US. Study 2 (N = 9508) analysed data from the World Value Survey and involved a larger, representative sample of individuals from the MENA region. Across studies, mediation analyses provided evidence for the hypothesized indirect effect of perceived corruption on life satisfaction through institutional trust. Implications of the findings, limitations of the studies and directions for future research are discussed
